HAY-LOADER.

Specification of Letters Patent.

Patented Got. 14, 1M3.

Application filed November 13, 1912. Serial No. 731,184.

To all whom it may concern:

Be it known that I, CHESTER J. PATTER- SON, a citizen of the UnitedStates, residing at Philadelphia, in the county of Philadelphia andState of Pennsylvania, have invented new and useful Improvements inHay-Loaders, of which the following is a specification.

This invention relates to hay loaders, and it has for its object toproduce a hay loader of simple and improved construction embodyingmechanism whereby the speed of the loading apparatus may be varied so asto insure efficiency of operation under varyingcrop conditions.

A further object of the invention is to simplify and improve the generalconstruction and operation of the device.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the Same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawings,Figure 1 is a longitudinal vertical sectional view of amachine constructed in accordance with the inven" tion, taken on theline 11 in Fig. 2. Fig. 2 is a top plan view. Fig. 3 is a sectionalelevation taken on the line 8-3 in Fig. 2. Fig. t is a horizontalsectional view taken on the line l4 in Fig. 3. Fig. 5 is a sectionaldetail view of the speed varying mechanism taken on the line 5-5 in Fig.4.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The frame A of the improved machine includes a tongue or draft member 1and side members :2, 2, the latter affording bearings for the axle 3having the transporting wheels 4, one of which is loose on the axle, butis equipped with a pawl or dog 5 engaging a ratchet wheel 6 associatedwith the axle, which latter will thus be rotated in its bearings whenthe machine advances over the ground.

The frame of the machine includes uprights 7 supporting the conveyercasing which includes side members 8 including between them adjacent totheir lower ends a drum 9 having hubs 10 that revolve on the axle, saidhubs extending through the side members 8 of the conveyer casing, asclearly seen in Fig. 4. The side members of the conveyer casin areprovided adjacent to their upper ends with slots 11 to accommodatebearing members 12 which are adjustable in said slots by means of screws13 and which afford bearings for the journals of a roller 14- over whichis guided the enclless conveyor B, which latter is also guided over thedrum 9. The endless conveyer is composed of a link belt, the links ofwhich 15 are provided with outwardly extending prongs 16. Some of thelinks or interspaces therebetween are engaged by the studs 17 on thedrum 9 which thereby serves to impart motion to the conveyer. Guiderollers 17' are provided on the inner faces of the side members 8 of theconveyer casing interme diate the roller 14 and the drum 9 to engage theupper lead of the conveyer, a portion of which will thus be maintainedin approximate parallel relation to the upper lead, as clearly seen inFig. 1.

The conveyer casing is maintained in an inclined position by the frameof the machine, the forward end being elevated, as shown. When thetongue or draft bar 1 is connected with the reach bar 18 of an ordinarywagon, indicated at C, in the several figures of the drawing, the upper,forward end of the conveyer will project over the tail end of the wagonbox so as to discharge into the latter. The side members 8 of the conveyer casing are provided near their upper forward ends with brackets 19connected by a cross bar 20 on which a plurality of guard rods 21 arepivotally mounted, said guard rods having curved front ends extendingforwardly of the conveyer, and said guard rods being extended downwardlyand rearwardly so as to extend some distance in rear of the conveyer.The side members 8 are also connected together by a cross bar or rod 21upon which a plurality of rake teeth 22 are mounted, said rake teethbeing also extended through a cross bar 23, whereby they are held inproper position for operation. These rake teeth are curved around thedrum 9, in approximate concentric rela tion to said drum for a portionof their lengths, as clearly seen in Fig. l. The rake teeth 22 are alsopositioned intermediate the guard rods 21, the lower ends of whichlatter project rearwardly of the rake teeth.

Mounted on one of the hubs 10 of the drum 9 is a sprocket wheel 24having a clutch member 25. Mounted loosely on the axle 3 is a sprocketwheel 26 having a clutch member 27 facing the clutch member 25. Mountedslidably on the axle 3 with which it is connected for rotation by meansof a key or spline is a double clutch member 2-8 which may be engaged bya shifting lever 29 fulcrumed on the frame of the machine at 30 to placeit in mesh with either one of the clutch members 25 and 27. Supportedfor rotation in suitable bearings at some distance from the axle 3 is ashaft 31 carrying sprocket wheels 32, 33 of different diameters, saidsprocket wheels being connected with sprocket wheels 24 and 26 by meansof chains or link belts 34, 35. It will be seen that when the machineprogresses over the ground and the axle 3 is rotated, motion may betransmitted from the axle directly to the drum 9 by placing the clutchmember 28 in mesh with the clutch member 25 of the sprocket wheel 24carried by the drum. If it is desired to increase the speed of theconveyer, the clutch member 28 is placed in engagement with the clutchmember 27 of the sprocket wheel 26 which is connected by the link belt35 with the relatively small sprocket wheel 33 on the shaft 31 fromwhich motion is transmitted by a link belt 34 guided over the relativelylarge sprocket wheel 32 to the sprocket wheel 24 associated with thedrum.

The tongue 1 is provided with a prop 3G hingedly connected therewith forthe purpose of supporting the frame of the machine when detached fromthe wagon. WVhen not in use, the prop may be supported by means of akeeper 37 From the foregoing description, taken in connection with thedrawings hereto annexed, the operation and advantages of this inventionwill be readily understood.

When the machine is drawn over the field, the hay is gathered by therake teeth and is carried by the prongs l6 projecting from the links 15of the endless conveyer beneath the guard rods 21 and is eventuallydischarged over the upper end of the elevator into the box of a rack orWagon with which it is connected. The adjustable bearings 152 permit theendless conveyer to be main tained under proper tension, and the speedof the conveyer may be regulated according to the condition of the cropby simply manipulating the clutch member 28 by means of the lever 29.

Having thus described the invention, what is claimed as new, is

In a hay loader, a frame, having a wheel carrying axle supportedforrotation, a conveyer casing including inclined side members supportedon the frame, a drum supported for rotation on the axle and having hubsextending through the side members of the conveyer casing, an endlessconveyer guided over the drum, a sprocket wheel fixed on a hub of thedrum and having a clutch member, a sprocket wheel loose on the axle andhaving a clutch member, a double clutch member slidable on the axle andconnected for rotation therewith, means for adjusting the double clutchmember to place it in engagement with one of the clutch members of theaforesaid sprocket wheels, a counter shaft supported in parallelrelation to the axle and having sprocket wheels of various diameters,and link belts connecting the last mentioned sprocket wheels with thesprocket wheels on the axle and on the hub of the drum, respectively.

In testimony whereof I affix my signature in presence of two witnesses.

CHESTER J. PATTERSON.
